Rita Ora dared to bare nearly all in a see-through dress at the Vanity Fair Oscars after-party. The singer's tattoos could be seen through the sheer black mesh gown and she appeared not to be wearing any underwear.

Not to be outdone, Russian model Irina Shayk also wore a daring black mesh outfit that left little to the imagination.

At the other end of the scale, Australian singer/songwriter Sia covered up, obscuring her face with a platinum blonde wig. At least we think it was her.
